Reflecting the state of a complex physical asset or process into its digital twin cannot be a perfect process. However, accurate reasoning must stay possible on a digital twin even in case of partial or temporary degradation of its connection with its physical counterpart. In the scope of an Industry 4.0 project, we are investigating how to deal with such a challenge for the optimised operation of a steel factory.
